If we've downloaded the new Pro beta, do we need to ask by e-mail for
a new license or are we supposed to use a feature within Maxi II to
get a new license sent to us?

I also noticed than after running Pro for the first time and then
running Maxi II that the window positioning was different than I had
used before. Are they both using the same preferences file, so changed
made in (or by) Pro may impact using Maxi II?
